On January 7,1610
Galileo observed with his telescope what he described at the time as
"three fixed stars, totally invisible by their smallness", all
close to Jupiter, and lying on a straight line through it. Observations on
subsequent nogts showed that the positions of three "stars"
relative to Jupiter were changing in a way that would have been
inexplivable if they had really been fixed stars. On January 10 Galileo
noted that one of them hade disappeared, an observation which he attributed
to its being hidden behond Jupiter. Within a few days he concluded that
they were orbiting Jupiter.

Leonardo's formal training in the anatomy of the human body began with
his apprenticeship to Andrea del Verrocchio, his teacher insisting that all
his pupils learn anatomy. As an artist, he quickly became master of Topographic
Anatomy, drawing many studies of muscles, tendons, and other visible anatomical
features. As a successful artist, he was given permission to dissect human
corpses at the Hospital of Santa Maria Nuova in Florence and later at
hospitals in Milan and Rome. From 1510 to 1511 he collaborated in his
studies with the doctor Marcantonio della Torre and together they prepared
a theoretical work on anatomy for which Leonardo made more than 200
drawings. It was published only in 1680 (161 years after his death) under
the heading Treatise on Painting.
